The 41-year-old revealed that when Emily, 23, moved in to his home, he didn't want to unsettle Princess, seven, and Junior, nine, - his children with ex Katie Price - so he and Emily didn't sleep in the same bed for a year.

"I didn't want the kids to get confused because they knew her as a friend," the dad-of-three explained.

"We still don't kiss in front of them now and we slept in separate beds for a year."

But despite Peter's best efforts to keep their relationship a secret – he didn't manage to fool Princess and Junior.

"I sat them down and said: 'Right kids, we need to talk. Me and Emily love each other. We've known each other for three years. I love her and I'll marry her one day,'" he said.

"Bista rolled her eyes and Junior said: 'Dad we're not stupid.'"

Emily, who is the mother of Peter's third child, 10-month-old Amelia, added: "I think we're quite protective because they're kids. We cuddle and we are more affectionate now. They're the ones saying: 'Dad, give Emily a kiss!'"
